The input to a channel is a bandpass signal. It is obtained by linearly modulating a sinusoidal carrier with a single-tone signal. The output of the channel due to this input is given by
$$y\left( t \right) = \left( {{1 \over {100}}} \right)\cos \left( {100t - {{10}^{ - 6}}} \right)\cos \left( {{{10}^6}t - 1.56} \right)$$
The group delay (tg) and the phase delay (tp) in seconds, of the channel are
A. tg = 10-6, tp = 1.56
B. tg = 1.56, tp = 10-6
C. tg = 10-8, tp = 1.56 × 10-6
D. tg = 108, tp = 1.56
